Can't really make a reliable recommendation without knowing what kind of brakes (disc? caliper?) and the brand/model of the derailleurs.

Not about the specific question but might be a factor anyway- As one raises the upper body weight shifts to the rider's butt. Often one finds that the narrow drop bar saddle to no longer support the rider with this increased weight. Also as the body becomes more upright there's a loss of pedaling efficiency, or the ability to apply as much power through as much of the pedal stroke as with the drop bars position. Often the rider finds that a more rearward placed saddle works better with an upright bar. The last aspect that many don't think about is the more upright body generally reduces the ability to "work" the bike. The reduced ability to lift one's butt off the saddle over bumps can mean more flats, some find that besides a wider saddle a wider rear tire helps too. Andy

First step is to figure a comfortable riding position. If you have a trainer you can sort out an approximate position between a no-hands upright and on the hoods. More upright might mean a shorter stem.
Since you are running a double chainring, a rear trigger shifter, road or mountain, with a front thumb shifter, for trim; plus it is a pretty no-brainer shift.
With road caliper brakes, you can use flat bar cantilever brake levers.
New cables and housing and you are set.

Thanks for your input, this project is for my wife , who has RA, and as a result has fused vertebrae in her her back and neck, she cannot bend her neck as I(we) do for normal cycling position. I got her an e-bike(upright vado) and she loves it and has made great progress, many times not using assist anymore, she has ridden our daughters bike which is 40 pounds lighter, and likes it, but she can't maintain the neck positioning on our 40+ mile excursions.

In terms of shifters this is probably what I would go with: https://www.microshift.com/models/sl-t09/ and brake levers probably these: https://bike.shimano.com/en-EU/produ...0/BL-R780.html
Though if she is looking for less weight I would try a Vado SL the regular Vado is quite heavy but the SL versions are quite light and easy to ride.

With Sora 9 speed the front derailleur has 2 different non compatible versions.
Are the components all Shimano or mixed with other manufacturers?

Shimano makes flat-bar Sora road shifters, SL-R3000 or SL-R3030 for triple chainrings. As for brake levers, you'll want dual-pull or cantilever-pull flat bar levers. For proper brake power, road calipers require a lever with a shorter cable pull than for linear-pulls or mechanical discs. Shimano, Avid, and Tektro, and Origin-8 are some good lever brands.
