I use them almost exclusively in my home wiring - they're so much more user friendly compared to wire nuts. They are not large at all - I find wiring that these take a lot less space in tight boxes than a wire nut since they're flat and you can push them to the back more easily: https://imgur.com/a/tGTUJd9 https://imgur.com/a/tGTUJd9 They make stab Wagos as well which I don't recommend, but the lever ones are great. You can work 'hot' if you need to replace a switch or anything (don't work hot blah blah blah). Much of my existing wiring is crappy 50s era copper and in some areas, aluminum -- so to add GFCIs where useful, I use either the levers to join copper of shitty provenance or the ALCU junction connectors and a bit of the paste.
