I think CT1 could cover all those uses. I've not done it myself because I have a load of open sealants for different purposes. CT1 is paintable but also very good in baths and showers.
Sealants Online is a great resource if you have time for a deep dive.
Top tip, pour a bit of bleach round the edge of the bath where you’ve sealed it and cover with paper towels (to soak up the bleach and help cover all of the sealant). Remove after a few hours and rinse - et voila, no more black mould.
Noted, not had that problem with it myself although I usually use it to stick the bath/shower tray to the wall and add a decorative coloured sealant on top, often from Mapei (usually Jasmine !!)
