For some time, LO includes a basic package of fonts with LibreOffice which should be available in differents OS. In recent versions, there has been a contest to encourage users to design templates and one of the requirements is to use one of these fonts to mantain separate OS compatibility with some documents. I think that would be a good idea to include the fonts in default install of LO or highlight them as recommended in software plugins.

We've a hard requires on the Caladea/Carlito google-crosextra-caladea-fonts fonts and a hard requires on the liberation-serif-fonts fonts because both sets metrically match common msoffice fonts and I consider them vital parts of the interoperable game. The others we don't need as strongly so there isn't a hard requires from LibreOffice on them. There is now weak dependencies in rpm but I'm reluctant to make use of them for something like that. So from the libreoffice side of things I think we have the vital bits covered, and suggesting additional default fonts to be installed alongside libreoffice is something that could be done with comps, i.e. https://fedoraproject.org/wiki/How_to_use_and_edit_comps.xml_for_package_groups
