Looks like I'm too late to add much to the conversation that hasn't been said, but I also would recommend obtanium. I've fully transitioned to it and don't even use the F-droid app anymore. (Though I do still use their repository through obtanium sometimes)
Hang in there. The degoogled android experience has a bit of a learning curve, but ultimately its much cleaner and more freeing. You'll get the hang of things pretty quickly.
