I like or hate drawing backgrounds depending on setting, and how many times I've been drawing it. I really like drawing organic stuff like forests, and drawing expressive living areas is fun when you don't have to do it too many times. Cityscapes, most interior places, anywhere with a lot of technical straight lines I really hate doing. I'm not very good at scaling, and they're a pain in the ass.
How I approach backgrounds, I just do it? Like, I draw out a grid, and the 1-4 perspective points so I won't have to use the ruler throughout sketching the page. I draw the foreground, then background, ink, color, and I'm done. Sometimes I study a bunch of city pics to get a good idea of what I want, or objects like crosswalks, cars and public trash bins.
Assuming you're a digital artist I can't really give you any useful tips, I draw everything traditionally so we pretty much live in totally different worlds. (What is easier or me may be hard for you, and what is easy for you is 98% impossible for me. Lol) I guess for general stuff, do a lot of studying and practice perspective, the more you do it the easier it will get. If you're having trouble coming up with stuff draw your living areas, go to the park (if you can, given current circumstances) and draw, maybe draw different areas of your town. Stuff like that can be intimidating, but as your experience grows so will your confidence.
