Yeah I would check which clubs are close as the first thing. For example my nearest 1/10th off-road club is 15mins away, my nearest 1/8th off-road is well over an hour away.
On-road vs off-road? I'd go to both and just have a look, see what takes your fancy. Off-road has jumps and the surface is inconsistent, which makes it heaps of fun. On-road is fast and technical, so very different.
Based on parts and your three preferences there, I'd say 1/10th scale electric on-road would be the easiest/cheapest to get started with.
