You've done your homework. As usual.
If it were me, I wouldn't sweat the straight-line performance. It has more than enough as is and, IMO, what makes cars truly engaging and a lasting joy to drive are other, often subtle, things - some of which you touched on (e.g. minimizing body roll).
Also, with the turbo, if power winds up being a thing, you can always add power easily and inexpensively with bolt-ons and a tune (e.g. a bigger intake and a more easily flowing exhaust with a safe tune could add 75whp, no problem). Way easier to add aftermarket power to a blown engine than to a naturally aspirated one (or an EV).
