For the use case you've described, it sounds like the Adventures->Quests interface may get you what you need?
Pick the end game quest you want to work towards from the quest list on the left (eg Plague's End)
Then under Requirements: you can click the quests you still need to complete to jump to them.
There's also Back and Forward buttons just below that to step back through the quests you've viewed recently.
If you prefer something more online, then the wiki has quick links to a quest's articles for required quests.
eg https://runescape.wiki/w/Plague%27s_End#Official_description
Then press [show] next to Quests: and there's links for the hierarchy of quests required for Plague's End.
Most end-game quests also are at the end of a quest series. You can sort the quest list by Series via the dropdown list in the top-left of the Adventures->Quests parent interface, which may get you something similar to the quest paths you seek (the quests series are listed in approximate difficulty+chronological order).
