Picking a WordPress theme feels like picking a design, but it is really picking a foundation. A bad theme slows the site, breaks on updates, and fights every change you make afterwards. A good one disappears and lets the content do the work.
Start with speed, not looks. A theme's demo can look fast because it has almost no content in it. Check how many files and scripts the theme loads, and whether it depends on a heavy page builder just to show a heading. Lightweight themes — the ones built to work with the block editor rather than replace it — usually age far better than the all-in-one themes with fifty built-in features you will never use.
Next, check update history. A theme that has not been updated in a year is a risk, not a bargain. WordPress changes, PHP versions change, and a theme nobody maintains will eventually break something — usually right after an update, when you least expect it. Look for a theme with recent updates, a public changelog, and a support forum where questions actually get answers.
Then test it on a phone before you commit. Open the demo on your own mobile, not on a desktop resized to look small. Menus, buttons and forms behave differently on a real device, and a theme that hides its problems behind a desktop demo will embarrass you in front of every mobile visitor.
Finally, resist the demo content. Themes sell themselves with beautiful photos and perfect layouts that your business does not have. Ask instead: does this theme make a plain service page, a contact form and a price list look good with ordinary content? If it only looks good with the demo's photos, it is a costume, not a theme.
A theme is not forever — it can be changed — but changing one on a live site with real content is a project, not an afternoon. Choose slowly once, and you will not pay for it twice.

The line that a theme is a foundation, not just a design, is exactly right. I've seen small business sites where the theme looked great in the demo but loaded slowly, broke on updates, and made every small change a fight. Your point about testing on a real phone matters most to me — that's where most visitors actually are, and a menu or form that works on a desktop resize but fails on a phone costs real enquiries. Checking update history and support before committing is cheap insurance compared with rebuilding a live site later. Good, practical checklist.
