Unless your headphone can't reach your desired listening volume when the amp is at max gain, then don't bother getting a balanced cable! There's no benefit. It's just a way for the audio industry to cash in money from naive consumers. Also if you insist on using balanced, you must have a balanced cable, you can't just feed a normal cable and use an adaptor for balanced output. It has no benefit and will fry your amp. Although balanced cables can be used with unbalanced output.
You could always hit up Periapt cables. They take custom requests and are reasonably priced. I'd personally stick with 4pin XLR or 2.5mm trrs as it's more versatile and there are a ton of adapters already. Not so much for 3.5mm trrs and 4.4mm pentaconn, sadly.
3.5mm trrs audiophile cables are rare... More options if you get a 2.5mm balanced cable and then just use a 3.5 trrs to 2.5 trrs adapter for the ifi
This is exactly what I do but I use a 4pin XLR to 2.5mm trrs and a 2.5mm to 3.5mm trrs that came with the MEE balanced 2pin sets. I don't think they're for sale here on MD anymore but they're built well, cheap, and work without issue. I believe the MMCX version through MEE are a bit more expensive.
