So here https://wiki.lineageos.org/devices/ you’d follow whatever steps for your device, but what I did for mine was replace the official OS files with the files from here https://download.lineage.microg.org/.
Edit: I typically wouldn’t recommend GApps unless you really, really like deep Google integration. From my understanding GApps basically turns Lineage into stock android but with a newer android ver, while MicroG is faux google that pretends google play services exists for those apps that require it (I don’t think there’s too many that don’t just expect a non-rooted device)
You shouldn’t have any issues, no. I’ve been able to use Google Maps myself since alternatives are garbage, but I don’t see any reason the other cloud services wouldn’t work
