What to do if there is no (I can’t find it in Google) font used in the layout?

Question

Fonts

In this case, I can't find font-family: HelveticaNeue;. I usually download a font and run it through www.fontsquirrel.com/tools/webfont-generator . If there is no such font in the public domain, what to do?
And another idea came up. Collect a collection of fonts, for example, if I'm typesetting and I came across a font font-family: Bitter; I download it, run it through www.fontsquirrel.com/tools/webfont-generator and put it separately in a folder so that if it happens again in the future, so as not to create it again through www.fontsquirrel.com/tools/webfont-generator . Is there such a practice? And then a lot of time is spent on connecting fonts.
