Glad it worked out for the OP;
I’ve used those tall, adjustable stems when building adaptive bikes for riders with disabilities or other mobility issues. I usually start out with a slightly undersized frame for ease of mounting/dismounting and starting/stopping, so I have to make the bike “bigger” and more upright.
I never liked the T-handle look of a flat, straight bar on top of a skyscraper stack of a steerer extension and a near-vertical angled stem, though; I like to fit a riser bar if I need to get a lot of height without adapters or super-tall stems.
Even my personal “Kruizer” has a mid-rise moto bar on a 50mm BMX stem for that high, wide riding position. I might be almost 50, but I don’t want to ride an “Old Man” bike

This thing is almost 4 ft tall at the grips (44”) and I’m only 5-10; it’s up there
