Can it show british grid reference

Yes. Default Position Format is WGS84 Hd.d but if you go to Settings > Navigation > Position Format and choose British (BNG) you’ll get your Location displayed as, for example, SU 0834 0456.

Does the watch share data with apple fitness app ?

I’m sorry I don’t know. The watch uses Suunto app which can link to strava.
