There are switches that are specifically designed to be silent. Getting them used to mean building a custom keyboard (which can be much easier than it sounds with hot swap boards) but I think they are more common now. You can check drop.com for a couple builds that should have silent switches and hopefully be wireless.
I found my holy grail in the HHKB Pro 2 Type S. It is not cheap by any means, uses a different switch type called topre and has a non standard layout that people love or hate. Fwiw I originally hated it because it didn’t have dedicated have arrow keys, but the fn layer arrow keys became muscle memory within a couple of weeks.
It’s wireless and pairs to multiple devices but it’s not for everyone. I haven’t bought another mechanical keyboard since.
This is probably the case. The only keyboard I’ve bought and will buy from drop nowadays are the Tokyo60s. Otherwise I use it for key caps or accessories.
