Answer 1

On account of the fact that the fake service sounds a little loud, but there is definitely some truth)
First of all, check the indicated services from tuxfighter , and you can also look at web.dev.
But, before that, take a look at how Google looks at the site in GSC, what is the bounce rate in Metrics and Analytics. Do people (visitors) have real problems with your site loading speed. Plus take a look at hosting - it can also slow down.

Answer 2

No, if you are making a site for google, and not for clients, then continue in the same spirit.
