Just had a quick look, but mainly trip advisor reports on sea caves, then came across http://www.cambriancavingcouncil.org.uk/registry/CoNW/CoNW_10.htm
But not very promising with regard to long trips.

Nothing wrong with Holyhead if you keep your windows up
and don't stop at red lights!
Actually, the breakwater park (the old quarry) and the walks on the sea edge there are very good.
Just no underground. https://angleseyisle.co.uk/breakwater-country-park

Fedw Fawr Pot and Fedw Fawr Pot 2 near Penmon. Would keep you occupied for 15 minutes. Ditto Castell Mawr near Benllech - another 15 mins.

There's karst on Môn but nothing on Cybi itself. If you want tourist trips there's a lot to pick from:
- for caves I'd go on caves of North Wales; now on the Cambrian website https://cambriancavingcouncil.org.uk/registry/CoNW/CoNW.htm
These are mostly in the East in the alyn and minera limestone
- for mines then there's a huge volume. Parys is fantastic (in the middle of Môn) but you'd be surprised how little time difference there is in getting to the mines on the mainland now with the A55. Personal favourites are the great orme (penmorfa), cwmorthin, Benallt, but there's a lot to choose from. I'd have a look on the archived pages of aditnow and see where groups like 'the Thursday nighters' have been and what they've enjoyed.

Wrong kind of rock at Holyhead for caving. Although it looks white from some distance away, the local rock isn't limestone and it's a very hard material. I believe they used it to form the ferry harbour breakwater, hence the disused quarry remaining at Breakwater Country Park.

There are 2 main geological formations on Cybi - the quartzite which is what Stuart is referring to and makes up the big lump of 'Holyhead mountain' and the alternating siltstone and sandstone that make up the South stack area and rhoscolyn which is where you can find many of the sea caves as these are much much softer.
There is a climb in the mountain (elephant's arse I believe?) that's the closest you'll get to a traditional caving experience and some of the coasteering around rhoscolyn has echoes of the caving experience if you're truly desperate.
A lot of Môn is limestone, just sadly doesn't seem to concentrate water to form much karst.
