tl;dr: Wait for Nextcloud version 25.0.2 and Update. See https://github.com/nextcloud/server/pull/34905
Found a “quick” (and dirty?) fix.
The information about the required 64-bit PHP in the admin overview sent me the wrong way.
Actually “reading” (RTFEM - reading the ducking error message) in the Nextcloud Data folder (nextcloud.log) does help.
Then I found [Bug]: TypeError: Return value of OCA\DAV\Connector\Sabre\FilesPlugin::OCA\DAV\Connector\Sabre\{closure}() must be of the type int or null, float returned · Issue #34674 · nextcloud/server · GitHub which if you scroll down tells you about a workaround.
This is the patch that worked for me. Also had to sudo systemctl restart php7.4-fpm.service. After that everything seems to work again.
Still I have to replace the hardware but this gives me some room to breathe …

We didnt plan to actively remove 32-bit compatibility but it seems like we did for 25 without knowing as we do not test against 32-bit which is why we removed 32-bit support in the first place.
