I've found black/grey turtlenecks to be a nice middle ground, and apart from the occasional "one more thing" (Steve Jobs) or Elizabeth Holmes comment, those tend to work well.
If Vint Cerf can wear a three-piece suit, so can you!

At two consecutive remote jobs with a lot of zoom time, I had the habit of wearing Tommy Bahama shirts - these are Hawaiian style shirts (or some of them are) that are expensive and perfectly made (e.g., the pattern matches perfectly on both sides of the buttons). My wife made sure I had a diverse collection.
I feel like if I wore that to a software engineering interview I’d run the risk of being judged as just not really getting the culture.
As I get older I found the nicer fabrics and older style more fitting.
The ritual of steaming, prepping while listening to podcast is great.
If they can't appreciate the effort. That's on them.
I have a bunch of nice clothes, life is too short to limit myself to just one style. Not extravagant of.course.
The places that have been the least strict about supposedly "professional" things like dress code, hours worked (etc.) have all been the most professional in terms of quality of work and mutual respect.
From that perspective, dressing more formally can be considered a signal of having the wrong priorities.
That said, while I don't think I would necessarily wear a suit to work, I want to use my dress-code freedom to dress up a bit, in a way that I think looks flattering.
Paradoxically, I would maybe shy away from the suit during the interview, but switch to it once you've been hired and established your credibility.
Jobs bought lots of them for everyone at Apple to wear, nobody accepted, and he kept them for himself.
Dark jeans can be fairly dressed up, but chinos are also a good option.
At the end of the day, every group of people -- all the way from ethno-national levels to your particular niche in industry -- have their social signalling implements, and clothing/appearance happens to be a very common implement.
