Tarptent moment and scarp too. Honestly tarptents whole catalog is worth a close look
If there is a trekking pole tent that seems perfect, you can consider getting dedicated poles for it. tentpoletech makes custom length poles, tarptent makes an adjustable length pole designed to be used instead of trekking poles in tents as well as fixed length poles, and six moon designs sells fixed length poles. Im sure there are many more brands doing it too.
The rainbow is my go to tent. the arch is an engineered gothic arch and the provided tie out points on the arch are at the mathematically optimum points. Using additional poles under the top spreader bar really prevents movement in wind. When using poles in the freestanding setup, those poles create more ways to anchor the tent.
if you're crossshopping with hilleberg then bigsky international could be worth a look. the chinook has always caught my eye.
All tents need to be anchored, freestanding or not. While freestanding definitely have their pros, imo not staking/anchoring shouldnt be considered one of them.
