The pros would use an akemi epoxy to fill then polish it with a rotary sander / polisher.
Grout will do the job but may pop out after a period of time as it’s a small joint.
To caulk blue tape either side then a very small bead I guess, probably wet finger finish. I’d do grout personally as it’s easy to remove if you mess up.
