Are there any continuos metal paths between the building? Such as water pipe, gas, coax, phone, etc...?

Not that I`m aware of at this time.I read 250.32 Not clear on the single branch part.Electricians here say you can run three wire but the best way would be go with 4 wire and the rod.Just would like to better understand if three wire is permisable in this situation legally. But also personally I`m lean towards the best way if it is better.

If your installing a panelboard at the workshop, than you don't have a single branch circuit going to the workshop, you have a feeder.

Regardless if you wire with 3-wire or 4-wire, a grounding electrode system will be required at the workshop building.

I don't think either way can be classified as "better". Both will provide adequate service and practical safegaurding.

Take a course on stray voltage and you will find out why the 4-wire method IS better than using only 3.

If you are not sure of metallic paths then you MUST use 4-wire.

Ground rod(s) are necessary at the second building.
