Someone has written a program in Python3 that allows you to search for any address on bitcoin core whether it belongs to your wallet or not. (I've not tested it personally so try on your own risk)

Here is the github link:

Its a bit old but let me know if it still works.

Sparrow wallet is amongst the top bitcoin wallets supporting taproot addresses.
I dont find an official ANN thread on it but dkbit himself opened an unofficial thread if you search for it.
