Go through the rest of the Deathbolt soundtrack for more of this style by Chris Christoudoulou, and then listen to the Risk of Rain 1 and 2 OSTs for a more prog rock style from him.

In terms of approachable jazzy ish OST, maybe Halo ODST's OST, even though that's way more downtempo. It's hard to think of other music that hits exactly this level of chill, but energetic and inspired. Bluesy, but electronic.

In terms of an utterly standout OST that features some jazzy tracks you could check out Katana ZERO's OST. there's multiple composers there and so more genre variety but it's an incredible soundtrack with a few jazzy pieces like Snow's Theme or Rain on Brick or End of the Road, but there's also more synthwave stuff on there that's all just standout.
