My go to shot for this slot is an Archer, I'm currently bagging both an ace race ESP disc and a Z plastic. For holes in the 250-280' the archer is great, anything longer than that and it's too flippy for me.
This was my first experience with plastic making a difference in the disc. The esp disc now gets used mostly for standstill approach shots where I don't have a forehand lie or 220-250' ish tee shots where I want to hyzer flip with late turn that doesn't fight back. Usually if I try to go any longer it'll turn throwler.
The Z plastic is great for 200-250' tunnel shots, on a bit of hyzer it'll flip to flat, drift left then finish with a baby hyzer (LHBH) thrown off the tee I give it 30-45 degrees of hyzer angle and let it flip to flat about 70-100' down the fairway, then lazily drift left before finishing back towards the center but still a bit left of the tee.
All of that said. The Archer may not be as long as you want. When I first started playing the archer was among my longest discs (thanks understability and glide) but as I slowly improve and my form gets better I'm able to put other "understable discs" like DX teebirds out into the 300-320' range. That has me on a similar hunt for a disc that flips and turns like an Archer, but can cover longer distances like a teebird. I suspect eventually my teebird will beat into that, and when that happens I'll live in fear of the day I lose it and have to start the cycling process over again.
