It took me about a year and a half to reach a point where I could start splurging on characters a little bit. Up until that point, I was mostly saving up for meta rolls and then investing into those.
In general, what you want to do is get the supports. Himari, Ako, Swimsuit Shiroko, Camp Hare, New Year Fuuka, Rio, Seia, Kisaki...those girls don't even need to be 5*, just 5/7/7/7 and they're mostly fully functional. The DPS you can borrow from raids until you can afford to max them yourself/roll for them.
You also want to invest into healers. Kokona, Serina and Koharu are the most important ones, you'll usually be using one of these on every raid.
After 2 or 3 BlueFes cycles, you should have most of the meta DPS units. Wakamo, Armored Hoshino, Dress Hina, Mika, Swimsuit Hanako...and you'll have the resources to max them out.
From that point forward, your resources are mostly free. Occasionally, new meta units comes along, like the upcoming Shupogakis and Swimsuit Mika, but you get resources at a higher rate than new metas come out. So you can start maxing out your favorite girls that are more situational.
