Some of my favorite books myself and ones I recommend are:
Joy of Living by Mingyur Rinpoche. These type of books on how to live a happier life are good even if you're not so keen on Buddhism.
Buddhism for Dummies by Jonathan Landaw. I don't like the title much, am I a dummy? Maybe in some things and not others. Still, a book like this is excellent because it provides an overview of nearly everything in Buddhism. An excellent foundation.
Introducing Buddha: A Graphic Guide by Jane Hope & Borin Van Loon. I like the Graphic Guide series quite a bit as they’re fun to read and provide a great start and overview. Buddhists are often comparatively quite uninformed of the Buddha’s life and teachings compared to other religions (such as Christianity). If you read Buddhism for Dummies, Introducing Buddha: A Graphic Guide, and What the Buddha Taught this won’t be you.
What the Buddha Taught by Walpola Rahula. A classic and good expose of the doctrine the Buddha taught.
Why Buddhism is True by Robert Wright Why Buddhism is True by Robert Wright pairs up quite nicely with What the Buddha Taught, as Why Buddhism is True eschews entirely the doctrinaire aspect of Buddhism in favor of Buddhism’s science of the mind. The pair of books make a nice combo.
and for Meditation, Don't Look Down on the Defilements, They'll Laugh At You by U Tejaniya. Read the chapter Right Attitudes Towards Meditation first. Grok it.
You can download his books for free from his website, https://ashintejaniya.org/
Jack Kornfield's The Buddha is Still Teaching has many short excerpts from various books and masters. It makes a nice book to pick up and read for short snippets. It's also good in that you can find other authors and writers you might enjoy reading.
Kornfield's Path With a Heart is a favorite and wonderfully kind book I've read a couple times.
A very readable book reportedly written by the Buddha is The Dhammapada. It's full of wise sayings you've probably seen on Internet memes. I recommend the Gil Fronsdal translation version of The Dhammapada.
If you like The Dhammapada, continue down the early Buddhism path with Gil Fronsdal book, The Buddha Before Buddhism: Wisdom from the Early Teachings.
Some top online options I want to draw your attention to are below.
Coursera. I recommend Robert Wright's Modern Psychology and Buddhism course. Free.

Tibet House, Delhi. Under Geshe Dorje Damdul. I've known several people who've taken this program and they rave about it. Check the schedule I think it only starts at certain times. There's a cost, but it's Indian pricing so it's very reasonable.

The Tergar center has programs that people like (e.g., “Joy of Living”) but you have to pay for them. Tergar.org
(Not Buddhism, but still good). Modernstoicism.com. Home of Stoicism week and Free Courses. Stoicism is good for practicing Equanimity.

If you can afford it, subscribe to the Waking Up app (currently $99 a year). If you can't afford it, they seem very nice and easy regarding free accounts. Email them. The app is impressive and has a lot of excellent content.
I have a YouTube dharma playlist with over a 100 videos here:

On Youtube, I like PBS's The Buddha and Samadhi Parts 1 & 2. Start with those. Doug's Dharma is a good YouTube channel answering some common questions or discussing interesting issues.
See on Reddit /r/Buddhism (check out resources on sidebar) and /r/NewBuddhists
Don't feel rushed into making any decision about what Buddhist school or sect you should join. You don't have to join any. There's also a big advantage in doing a general survey of Buddhism before making any decision. It's nice to be free to learn from different wisdom traditions. Why label yourself? Why limit yourself?
A very common question beginners have takes a form like: Can I do or be X and still be a Buddhist? -- Where X can be anything from playing violent video games, to fishing, to being a cam whore, to being LGBT, to being a soldier, to helping a friend cheat on a test, to feeding your cat meat, to euthanizing a sick pet, to eradicating bedbugs.
There's no theological entrance exam to become a Buddhist. There's no one who's gonna kick you out of the Buddhist club and take away your Buddhist membership card no matter what you do or believe. Opinions may differ. We're done with the era of hunting down heretics that don't believe in the one true faith (coincidentally the one who is gatekeeping believes in). So it's simply more practical to give up gatekeeping. Ignore annoying gatekeepers and follow your heart.
My .02 is to try to Be Mindful. Do no harm. Try to practice equanimity and be kind to others and yourself. Try keeping the Precepts and practicing the Brahmaviharas. Don't just react. Too much of anything can be bad. Hold onto things lightly, including points of view. Have a sense of humor and a sense of wonder. Relax, and Be Aware.
Keep it simple, don't make it too complicated for yourself, especially at first.
I have a Guide to Dharma Books & Practice here. It has many links and resources as well as a suggested Independent dharma study options (includes nearly all resources necessary). It also has a Frequently Asked Questions (FAQ) at the end:
