Sorry if I have dug up yet another covered to death topic

My verada restorer has the old slow power windows, particularly front passenger side

Ive never read about what people do to fix this, is it just the window tracks getting gunked up and need cleaning?, they sound okay, just seem to be under more load the slower they went

Or is it something more sinister?

It could be a couple of things. The contacts get dirty in the master switch regularly.
The tracks require lubrication - there is more than one. A rubber track sits at the very front of the door panel and usually are never lubricated.
The cable has frayed for the mechanism.

The main culprit tends to be the tracks, they need regreasing from time to time, but it could also be any of the things mcs_xi mentions. Most mechanics and/or auto electricians should be able to sort it for you relatively cheaply.

A rubber track sits at the very front of the door panel and usually are never lubricated.

If the track should be lubricated, what lubricant is recommended given that it is rubber?

One would assume silicone?

Have this problem too. By rubber tracks we are talking about something internal to the door? Not the rubber seals for the window glass?

Yes, more than one internal window track. Take a door trim off and shine a torch at the front cavity in the door.

There will be a rubber window guide. These grip the glass and strain the motors. Swim them in lithium grease, same as the metal main window track. Should double the speed.

'the google' says not to use lithium grease (or anything petroleum based) on rubber as it can degrade it or cause it to swell. Silicone spray is safer on rubber

I just used wheel and bearing grease by Valvoline, when I tidied mine up.

I did have to remove some of the grease as you dont need a great deal.

I would have thought something like drylube would be sufficient, or am I wrong?
