There are a couple of other models but they're older, the Fenix 8 and Enduro 3 just came out earlier this month or late last month, I forget as time flies. But there's the Forerunner 955 and 255, then there's the Instinct 2 series (2S, 2, and 2X). There might be others I'm forgetting, but I'm assuming there isn't likely to be a lot of MIP options going forward.
Coros watches are MIP though, which I would probably switch to if Garmin stops making affordable MIP watches... the pricing on the Fenix 8 and Enduro 3 are nutty. $800+
Compared to my watch set to the lowest sleep mode brightness, the brightness in this image is not set to the lowest level (probably for the purposes of showing the sleep mode watch face features), but this gives you some idea:
