Any suggestions on how to fix this in templates? E.g. nl:Sjabloon:Infobox werelderfgoed has a link at the bottom, which gets passed as a parameter to the next template.

I don't have a good easy suggestion for you right now.
But, looks like enwiki is fixing some templates ( https://en.wikipedia.org/wiki/Wikipedia_talk:WikiProject_Trains#Sydney_styling_in_Template:S-line ) to address similar issues. I am not sure if what they are doing is relevant for you or not.
Thanks for the link. The idea that links should ideally be visible as links, is a good argument to remove unnecessary styling.
