A little defense in depth should be ok if you can stomach the hassle.
Consider making a small veracrypt container (around 10MB) before uploading while you are at it. Its a hassle though but I’d consider this safer than say Bitwarden.
I hope the password vault doesnt change too often because uploading frequently is a hassle.
make sure your keepass db has a strong password, 100 bit of entropy is a good balance. then you are uploading to e2ee cloud drive. bro you are good dont worry
