That works okay if you are the only user.

I use quite a few Nextcloud features where access via tailscale is either inconvenient or impossible. My whole family uses the calendar on their phones and other devices, which means they would have to either learn about VPNs, or I would be the one managing all their devices for them. (Neither are likely to happen.)

I also often share individual files or folders with external contacts as a more private alternative to dropbox or google drive.
