For work, aside from Office (that would have an ARM64 port), the only 'native' x86 application on Windows 11 I run is 32 bit, unsupported and hasn't been updated for a decade. So as long as the binary translation is capable of emulating with the speed of a Pentium 4, that would suit fine.
Anything other than that uses a mixture of language specific dot net, Java or JS (Electron) VMs - which surely JIT ARM64 natively by now.
But depending on the era of the software, something released in the past 13 years (WIndows RT in 2011) is likely to have been developed with a reasonably modern version of Visual C++ that includes a 'compile for ARM' checkbox with compiler warnings to help you migrate. Not a trivial task by any means but if your vendor is still in business, ask 'em for a recompile!
Gaming, well that's potentially another story but who games on a low performance laptop anyhow? The bigger picture is if and when Qualcomm loses its exclusivity deal with MS and nvidia release a series of Win 11 laptops running Tegra Thor inside - then it really will be game on :)
