Here, for reference, is a brief list of reasonably readable sans-serif fonts with not-too-heavy boldface and a fairly distinctive italic variant (so as to be suitable for use as a comments text font, in accordance with the desiderata suggested in my previous comment):
Frutiger Next *
IBM Plex Sans
Optima nova *
(Fonts marked with an asterisk are those I personally am partial to.)
Edit: Added links to screenshots.
