> The part I struggle with the most is that I don't have anyone I feel comfortable talking to about the daily challenges that my team and I face.

This should be your manager. Are they in the same boat as you? (New to the org?) If not, start there.

I work at a globally distributed company, and post-pandemic I'm seeing relationship building being a challenge happening more. Pre-pandemic, the company would get together every 9 months and I do think those times really help to build relationships.

You need some "team building". Someone below mentioned pairing and I agree, but also consider spending $5 on amazon luna and play some jackbox games. The recent pack has a game called Job Job that was really fun in a work environment. You answer benign questions and then you are asked to answer an interview question using only other people's answers. My all remote team really enjoyed it.
