My parents live on the island and back in 2017 me and my dh stayed here for a few nights as a treat after DD was born, parents had her a few nights. It was glorious, couldn't fault it, but apparently it's really gone down hill, so disappointing.
If you're willing to travel, betws y coed is great in the rain because it makes the waterfall very impressive, and they have really lovely cafes and a pub. Probably about 45 mins if you go through the valley and a really impressive drive with high mountains either side. One of my fave places and I always go there when I'm visiting parents.
Beddgelert is also lovely, very small but lots of independent little shops and great cafes, also quite atmospheric in the rain and again a lovely drive to get there.
I lived on Anglesey for 10 years and have to say, there's not a lot on the island when the weather is bad, but then I was in my late teens / early 20s and suppose found it boring! During the summer it's a haven, beach parties and paddle boarding every weekend 🤣
