I’d like to request a blur tool that varies the degree of blur between paths.

Much how contour lines on a map indicate altitude, the path would set the blur radius.

Not to be confused with the path blur you get in photoshop; it’s closer to a field blur, but instead of radial points it uses vector paths. I really dislike using masks on blurs as it looks unconvincing. I’ve tried other methods for realistic focal depth on a 2d image (painting my own z-depth, multi layered blurs, etc) but they are quite a lot of effort to make. I feel this method would be the quickest and easiest if only it existed!

If this tool already exists somewhere/anywhere, please let me know!

I’ve tried to illustrate the idea below (excuse the lame character)...

Thanks, but on irregularly shaped subjects (that aren’t linear or spherical) it still looks faked. Rather than following the contours of the subject, the DOF Blur transitions  are restricted to oval or linear. I actually used a combination of DOF and Field blur to make the illustration (although it’s not an entirely accurate representation).

However, you are right - and I should amend the above comparison - it is essentially a depth of field blur. Although, instead of being limited to oval or linear transitions, I’d like to be able to manipulate and add nodes like you can a vector shape... and also, add extra transition points (paths) like the gradient fill tool.

I understand your request, and it should certainly also apply to realistic adjustments to standard photographs. But I'm afraid the feature you requested is already quite specific and difficult to implement, so I wouldn't expect to add to Affinity products too soon.
