Assuming SMAPI (the modloader) has updated for 1.6.9, this page is a pretty comprhensive list of mod compatibility with the latest SMAPI and Stardew updates.
It'll take a few seconds to load.
I also find that it can be helpful to check community news posts for the most popular mod packs (usually on their discord), as they do a pretty good job of announcing whether the mods they shove together work yet or not.
All that said, 1.6.x type updates, where they aren't incrementing the first or second number, usually don't break as many things. Personally, I'd just make a backup of your entire Stardew folder before you install the 1.6.9 update (and the latest SMAPI update, and any updates for your mods) and see how it goes. SMAPI will usually warn you in the console window at startup if it sees any mods it knows have broken. If shit's fucked, just restore your backup copy and try again in two weeks.
That's just fucking evil. Better than using some barely audible tone that hooks into the primal parts of our brains to make us uncomfortable and anxious (those supposedly exist), but even what you've said is just literally psychological warfare tactics.
Seriously, the CIA (or the equivalent) during the Korean War used to fly over vietkong areas blasting that sort of shit to disrupt sleep and demoralize them.
