I see a tremendous gap in the offerings which needs be filled by some enterprising company.

Pistol, single stack, semi-auto, 9x19, 9x17 (.380) or .22LR.
Striker fired, (now for the good parts) tip up barrel loading, with positive extractor, locked breech, low recoil, DAO, easy to field strip with take down lever.

Size less than 7" long, 1.2" Wide, 4.5" high. Most people should be able to get all fingers on the grip. Sights: night, Novak compatible key slots in slide or equivalent commonly available sights.

Who would buy one from a reputable manufacturer...with known reliability.

I envision something like a SIG 320, with the firing unit and interchangeable components, I've been spoiled by the AR pattern rifles.

The tip up barrel and locked breech would require some engineering brilliance. A sled between the frame and slide allowing them to move and unlock, with a block locking system like an M-9. Positive extraction could employ single or dual extractors at 9 and/or 3 o'clock, pushed apart by the end of the chamber then engaging via slots.

Recoil could be reduced using a longer slide travel and multiple springs.

It's an interesting solution to the arthritis problem many of us are having.

The reason Beretta hasn't put an extractor on their tip up barrel guns is because it won't work. To accommodate for the downward movement of the cartridge you'd have to have an extractor with a rim cut so deep that it wouldn't be against the rim when the barrel was closed, so it would come back and strike the brass rim and either eventually break the extractor, or have a tendency to rip case rims off.

If you keep the chamber on a Beretta 86 clean, they are very reliable pistols.

So sans the extractor the 86 meets your requirements.
