I think it's safe to say that whatever you decide upon, some people won't be happy with it, others will be......

Whatever you end up using, just do it the best you can. At the end of the day, every track is different. Sand filled astro is not the same from one track to another. It's similar,....but not the same.

Indoors is a bit easier, due to not having to deal with weather changing the surface.

Personally, I would steer clear of anything that is going to give you more work to do.

Dirt - Lots of maintenance (Just look at the USA tracks and what they have to do to keep the surface consistent throughout a race meeting)
Sandy Astro - Outdoors, fine. Indoors, you'll just end up with loads of sand to clear up.

New Astro/Carpet - Virtually maintenance free, lots of grip and no one complaining about dirty cars or sand in their diff

My only suggestion is that you cover the jumps with the same surface. Whatever that surface is, keep it consistent. Wooden faced jumps are a nightmare IF you aren't a totally consistent driver.

Good post dude
