Yeah, this whole thing has made me wanna hear other songs in this style. But there do exist stripped down versions of some of these, as I'm sure you're aware; but if others aren't, I thought I'd compile a list:
The previously mentioned
A Sort Of Homecoming arrangement from JT30
https://www.youtube.com/watch/Po64SV4IKJM
For
Running To Stand Still, there's Edge's solo performance on Feedback Kitchen from 2015 , and also Bono's The Busk performance from Christmas Eve 2021...I prefer Edge's version but YMMV

https://www.youtube.com/watch/8EAuep7vUdQ
For
Love Is Blindness, there's Edge's solo performance from From The Sky Down
https://www.youtube.com/watch/12d-5Azr6PI
The Bono/Jools Holland version of
Velvet Dress isn't exactly a fully stripped-down version, but it kind of is, and it's a great rendition

Acoustic B&E
Please from Elevation Tour - Providence is my favorite but it's not on YT, so here's Miami:

For
North And South Of The River, there's its lone live (pro-shot) performance from the Omagh tribute, which is way more stripped down than the studio take.

For
The Ground Beneath Her Feet, they've only ever played it acoustically, but there's one take I'm particularly fond of from the TV show TFI Friday in Dublin from March 2000 when the song was brand new

There was the acoustic
AMAAW from the ABOY single. And obviously there are several officially released live acoustic
SATSs(Mexico City and U2 Go Home are tops for me). Meanwhile, stuff like
First Time, Summer Of Love, Fast Cars, Drowning Man, etc are practically unplugged to begin with.
And some others not on that list:
Bono's solo (and abbreviated)
So Cruel from From The Sky Down
https://www.youtube.com/watch/MBq3CgBWlx8
'Baby'
Tryin' To Throw Your Arms Around The World
https://www.youtube.com/watch/7QeIvWSyTEk
The famous unplugged
Acrobat rehearsal from 1992
https://www.youtube.com/watch/xPSbe3-230A
Bono and Edge doing
Van Diemen's Land acoustically in 2008
https://www.youtube.com/watch/vsD95EE69Rk
Acoustic
Original Of The Species from "compilation CD 'Every Mother Counts 2012'*produced exclusively to*Starbucks Coffee Shop" - it's basically the early Vertigo tour arrangement with some strings overdubbed. I only just realized this exists, but happy for it because I always loved that Vertigo Chicago version.

Acoustic B&E
In God's Country from Elevation Tour, specifically the same Miami show as Please above is a good one
https://www.youtube.com/watch/mYI2SHsE-K0
A semi-acoustic
NLOTH from 360
https://www.youtube.com/watch/0LLKgExR5vo
Not really unplugged at all and probably doesn't belong, but that stripped down full-band
Crumbs From Your Table that was included on the DVD w/HTDAAB deluxe version
https://www.youtube.com/watch/HH2j4cIKUhY
'Baby'
One, which I prefer to the SOS version:
https://www.youtube.com/watch/qeCBPipTVF4
And from official releases...
Yahweh from Vertigo Chicago and
Wake Up Dead Man from Elevation Boston/U2 Go Home.
