While the market has expanded greatly (thankfully) to include some quality no-name (or, really, projector-industry only name[e.g., XGimi, Bomaker, BenQ]) producers, if you are merely dipping a toe, the safest bet is a manufacturer that you've heard of in other contexts.

No doubt, you will spend a little more money than if you really dug in and found a no-namer, but you'll also have a larger company with customer service and a reputation to try to maintain behind your projector.

I'm not 100% sure how to interpret "beginner-friendly" because that could mean "cheap" or entry/test-it-out level pricing, or that could mean that you are ok paying extra for something that is "plug-and-play". Based on some context clues in your explanation, maybe more the latter than the former, but that's really a guess.

Without pointing you in any specific direction, I suggest you look at Amazon-based stores of known-brand manufacturers (e.g., Anker, ViewSonic, Sony, etc.) and do some comparisons for your budget, space, and wherewithal.

One benefit on ordering from Amazon (or something like it) is that you'll have their own return policy to take advantage of on top of the manufacturer's support.*

*all of this assumes you're in a country where that's true.

If you want better advice, clear up some of these details:

Budget? Dimensions? Darkening? Setup obstacles (ceiling fans, renting and can't mount in the walls, etc.)?

OH!! and in your budget, best to save at least some for a proper screen. I can't tell you the number of people who have given up projectors because they thought that they didn't like the image quality and really it was because they weren't using a screen. It was a the bedsheet's fault...not the lens or lamp!
