I’m thinking of going with a GPS speedo when (and if) I swap out the factory gauges.
Anyone use them? Pros? Cons? Would you recommend them?

My Dakota Digital rtx have the GPS speedometer option. One disadvantage is if GPS signal is poor and so will the reading. Didn't get that option so I can't personally say anything about it
I have a Speedhut GPS speedometer.
PROS:
Accurate speed reading regardless of gear ratio or tire size changes.
CONS:
Occasional signal loss in parking structures and tunnels.
Even with the occasional signal loss, I would recommend them simply because a speedometer gear change isn’t needed with transmission, rear end gear ratio or tire size changes. I’m currently running a C4, but will swap in a 4R70W when my new engine is ready. That would have required a speedometer gear change if it wasn’t already a GPS speedometer.
I also did a diff. swap from a 2.80 open to a 3.55 LSD 2 years ago. The GPS speedometer didn’t care.
As for signal, it doesn’t matter if I lose signal in a parking structure or tunnel. Those are the places where I’m more interested in not hitting someone than what the speedometer says.

Since you were recently looking for a T5, a benefit would be using a T5 from a 99-04 3.8L V6 (ID # 1352-260) for the better gearset and torque rating without having to worry about adding a speedometer gear and Foxbody or 94-98 tail housing.
Whichever way you go you can always check your speed on your phone with Google maps (GPS speed), it displays posted speed and your current speed.
Speedhut. I have them in two classics and have no issues with them. As a bonus your classic never ages with the speedo disconnected.
I got the Cobra Road Scout. It's not only a GPS speedo, it's also a radar detector and dash cam.

Cons: Signal loss in tunnels or parking structures.
Pros: Signal loss in tunnels or parking structures. (I'm sorry, officer... my GPS speedometer stopped working....").
