On mobile, I've been using NOS2X as my NIP-07 signer on android. I've also used it on Desktop. iOS users tend to use Nostore.
For wallet, I've been using my own node, with LNBits to provide LNURL (lightning address) and Nostr Zap support.
If you don't want to run you're own node and manage that, then Alby Hub in the Cloud is a decent option. Beyond that you go more custodial with fountain, wallet of satoshi, strike, etc.
