Stand over height is only important when you are stood over the bike
As someone with short legs I disagree, it’s also important to have clearance to allow you to move around the bike on the trails, constantly banging your knees or thighs on the TT when you’re trying to move around on techy bits, jumps and berms is annoying and a hinderance.
Much more important that the bike fits in other ways
Important that it fits right in all the ways, there’s no need to make a compromise really, there are many many bikes out there.
Although…OP you didn’t mention road or MTB, if it’s road then I agree and ignore the above.
