I've only looked briefly into APC/UPC adapters, although my intention was to do the opposite of your scenario. In my case, I already had LC/UPC terminated duplex fibre through the house, and I want to use it to move my ISP's ONT closer to my networking closet. That requires me to convert the ISP's SC/APC to LC/UPC at the current terminus, then convert it back in my wiring closet. I hadn't gotten past the planning stage for that move, though.
Although your ISP was kind enough to run this fibre for you, the price of 30 meters LC/UPC terminated fibre isn't terribly excessive (at least here in USA), so would it be possible to use their fibre as a pull-string to run new fibre instead? That would avoid all the adapters, although you'd have to be handy and careful with the pull forces allowed on a fibre.
But I digress. On the xcvr choice, I don't have any recommendations, as I'm on mobile. But one avenue is to look at a reputable switch manufacturer and find their xcvr list. The big manufacturers (Cisco, HPE/Aruba, etc) will have detailed spec sheets, so you can find the branded one that works for you. And then you can cross-reference that to cheaper, generic, compatible xcvrs.
