Is it possible to create RGBI Cloud Optimized Tiffs with JPEG compression?

I guess you mean RGB and I for Infra-red ? Anyway the answer will be NO. JPEG
only allow 3 bands + a bit mask (same for Webp).
For raster with more than 3 bands there is no real option to get compression
(with loss) as high as with JPEG or WEBP .

Travis,
The big benefit of JPEG compression comes with YCbCr color space which I do
not believe can be mixed with a 4 band RGBI product. So I'm not sure how
one would do this. One could certainly put the NIR in a distinct directory
in the GeoTIFF, but not many applications would know how to util

Possibly. But not with the COG driver, which doesn't offer the option
for that. You should use the old way with the GTiff driver by forcing
-co INTERLEAVE=BAND
Thanks all for the feedback!
Right now we are looking at doing this for only 8bit.
