All comments: 'just get dot com'
I had the same question and went with .co. I think .io is falling in popularity due to dns scandal. More and more people are using .dev now and .ai is also ok.
Problem with .co is people tend to assume it's a typo outside of tech (eg my bank).
A lot of startups I follow moved to .com after a few years so I assume there are more pain points that I haven't discovered yet.
My intuition for ranking is something like
.co
.dev
.ai
.io
But would love to see data on trends by company size etc if anyone has.
The top 4 gTLDs seem to be .com, .org, .net, .co. dot com clearly won't make the cut for you but have you considered .net?
Interestingly, [1] led to https://ntldstats.com and this has a nicer graph based data. I found that .xyz has a 9.3% market share overall which is interesting as well.

Based on the contact form spam, my sites receive, don’t get .xyz, .site, and .online. I am sure, there are others like me, who block these TLDs.
Also, don’t get a region TLD, if you are not planning to serve that region.

Also, .com is easy to share via word of mouth. It's more work to say "yeah it's salt, then dot ly" than "salty dot com".
.com
.io
.fyi
.co
.net
.xyz i have not seen anything noteworthy on other than personal sites.
i feel like .fyi is going to blow up in the next 10 years. there are TONS of good .fyi domains available and they are typically arount $8 to register as opposed to the $34 .io domains.
If it's a commercial endeavor, I would urge you to get a dotcom and get creative with the name. A long-ugly-hyphenated-domain.com would be taken more seriously than a short LLL.WEBSITE or LLL.BLUE or whatever.
