I have seen a large number of "archived" requests for this feature in the forums dating back to *at least* 2017.
As a software engineer myself, I'd be really, really surprised if making parameters sortable or searchable was really difficult, given how well Fusion works in general. I can't imagine that your engineers have coupled the visual ordering of parameters in a list view to their actual implementation, that seems totally insane.
It actually becomes a major time suck trying to find parameters in a large list of them. I have a simple cabinet design with no moving parts and already have about 30 parameters and I can't imagine designing complex assemblies with moving parts and trying to stay sane with this.
You guys have said for (at least!) half a decade now that it's on your road map. There is obviously overwhelming support for it, just search your own forum, this request has been made over and over. Please consider prioritizing this kind of feature, the quality of life for users would just go through the roof.
Also, its really important to note that many of these requests are from people who have just started using the software - that is to say, this is a major pain point that affects every tier of user across your user base, not some just advanced users using a niche/fairly less-commonly-used feature. Thats why this issue should be prioritized, I would bet that nearly every single one of your users who are doing parametric design processes wants this.
