I think the terms you’re looking for are “choc spacing” and “MX spacing”. Choc spacing is what the Piantor uses where the space for each key is 18 x 17 millimeters. MX spacing is 19 x 19 millimeters.
If you want to keep using low-profile switches, there are a handful of boards that either choc or MX switches, and any of those will always use MX spacing. That said, I don’t think there are a lot of pre-built options in this space.
Maybe check out Klor. I think that one is offered as a pre-built by beekeeb and it uses MX switches. It’s got the more aggressive pinky stagger, but it also has some splay which may or may not be your thing. I just finished building one using tecsee “medium” switches and MTNU keycaps, do it’s lower profile, but still not as low as choc.
