Did you transition or quit cold turkey? I switched to Lineage OS with micog. Actually, now that I look through what I installed via Aurora, I'm surprised how few apps there are. 3 required for work. I guess I could reduce that to one with some effort. A few financial / shopping apps that are nice to have vs using their website. Google maps (not sure the replacement to that is).
I've found it to be more than good enough. There's also various OSM based apps:

It’s not quite as polished as Google Maps, but I use it as my primary maps app and have mostly not been disappointed.
I keep an iPhone 7 for corporate apps, but I'm on a Pixel 3a XL that hasn't talked to Google since I bought it.
OsmAnd~ is great :-)
I uses a separate app called GPS Coordinates. I give it an address and it gives me lat/long which I paste into OSM. I'm sure there's gotta be a better way.
