This got me thinking and if I can ask something. If I do not care about how/what comes up when people share, for my personal website, should I care about any of these OG/Twitter/etc?

Do you just ignore and move on (I mean from these meta tags and the like -- not this particular tool)?

Some will use the very first image found in your page, or generate a preview that may not look good. If that doesn't bother you, then you shouldn't worry about it. You might be better off just having a logo for your website, or something that represents your "brand" or "identity" where it's the same for all pages, just so you avoid having a bot creating something for you in the future (which may not align with your ideas).

There’s an SEO factor to some of these tags too, if you care about that. But otherwise no, feel free to not bother with them.
