If you are a new webmaster and you're looking for a domain name to purchase, it's a good idea to avoid the .xyz TLD.
The .xyz is much cheaper than .com, but, because it's so cheap, it's frequently used by spammers, scammers, and websites infested with malware. As such, .xyz is often added to BLACKLISTS, as in the WHOLE TLD IS BLOCKED, and your website is going to be blocked just because it uses the same TLD many bad actors use.
This could prevent you from commenting on a blog using your domain name as your website, from registering an account on websites using your domain name as your e-mail address, or even limit the visibility of your posts on social media.
What if I told you there was a way to instantly increase your email deliverability, website accessibility, the number of social media posts, and the customer perception of your brand? We just did exactly that by switching our primary domain from spot.xyz to spotvirtual.com.

Why hackers love .xyz and other new top-level domains
“The reason hackers like this [method] is you can register a domain under any top-level domain over and over again,” said Janne Kauhanen, host of our Cyber Sauna podcast. “So, for example, if Microsoft.com is already taken, Microsoft.xyz might not be.”

On top of that, some people will just not visit your website if they see it has a .xyz TLD because it's fishy. If you plan to have a .xyz to get conversions for a product or service, you'll probably lose some money because of this TLD choice. It WILL STOP people from from accessing your website.
Although there are countless TLDs today, it's still a good idea to use a .com TLD if you can. This website, for example, virtualcuriosities.com, has a .com TLD. You see how long this domain name is? The second level virtualcuriosities is 18 characters long. Some people may advise you that it's a terrible idea to have a domain name so long, and they are probably right. But I still think it's better to have a long .com domain name than having the perfect domain name with a .xyz TLD.
Personally
If I see a .xyz domain, I immediately assume it's a spammer's website or some scam. This blog was made with WordPress, so I get an immense amount of comment spam, much of which linking to TLDs like .xyz, .gold, .club, and so on.
If I see a .io, .ai, or .app domain, I immediately assume it's some AI startup or a cryptocurrency scam. This is just my personal opinion and my impression I have of these TLDs. Every time I come across these TLDs on Google, I know I just found a SEO spam article trying to sell me something. After a while it just becomes a stereotype.
In particular, I feel these "unusual" domains are typically only purchased by web developers and people with some technical background. If you are a normal person, you wouldn't get a weird TLD like these. You might get .blog because Tumblr sold you that. But you wouldn't get .io or .tv, which are country-level TLDs owned by foreign countries.
If I see .com, I assume it's at least a decent business.
If I see .net, I think it's a bit unusual and nerdy, but it's also a decent website.
If I see .org, I feel it's a bit pompous. I don't know why, I just think "organization" sounds pompous. Even if it's an actual organization.
If I see .info, I think it's a website full of ads. I think it's still an actual proper website, not a scam, it's just going to be full of ads.
What I mean by this is that which TLD you choose may affect people's perception of your website before they even click on the link. If you choose something with a terrible stereotype attached to it, you'll lose clicks just to save a few dollars per year on a decent TLD.
