Glad you got it all sorted with Dougs’s help.
I use self hosted fonts, because I have bought ones and I’m in the UK, so following GDPR as best I can.
I use Joe Workman’s Font Pro stack, which is expensive for just changing the font but I wanted to do some other things to the font display too.
If you were looking for a Helverica Neue équivalent try Google’s Roboto font.
