while i'm currently using sqlite, since it has only one write transaction at a time, if I understand correctly, opening a tx and doing outside requests while in the transaction could potentially block your whole application if the outside requests keep timing out... so you kinda need to watch out for that

Treat transactions like mutexes has always been the prevailing wisdom has not not? Keep them as short as possible and do not make blocking calls within one.

This would be true for any database, something read / written during a transaction would block at least that table universally until the transaction is finalised.
