While we’re looking at solutions, why not look at tried-and-tested solutions to the MF gear problem? It’s not a bad idea to look at the successes of other games and adapt and even improve on them.

TLDR: cap MF, give 1% bonus MF (and GF maybe?) for every level up past 80. Call em Ascension levels. This bonus can be nonstacking with MF gear, or alternatively, place a hard cap on MF from gear/food at like 100, and let the MF booster and guild boosters go past the cap. This would mean that if you have MF gear, it would quickly lose usefulness as levelups past 80 are fairly easily attained so it would not be a good investment to make an MF set temporarily. Why use MF gear, when at a few levels in and an omnombar, you’d already be pushing the cap? This lets people who want MF asap, to rethink their usage of MF sets. At a certain point, you would also have no point in using MF food, which is the predominant food of use. This would encourage more broad, dynamic choices in food for gameplay whether it be life on crit, or endurance regen, or might boons and whatnot, which would solve the current staleness of only using omnom/raspberry peach bars no matter what you do.
P.S. Also, give 2 Gifts Of The Ascended upon reaching the max Ascension. Let these be used in crafting an Ascended armorset (full box of all 6 pieces), and an ascended weapon. This would be a good solution to provide characters with access to ascended gearsets, without having a large impact on the economy, and also rewarding players for long term dedicated play. Make achievements for each 10 ascension levels, give a title “The Ascended” at either max Ascension levels or upon equipping a full set of ascended gear (armor, weapon, accessories)
