None of its findings points the other way.
Studies of Amyloid-beta 40 measured 1 outcome; the most studied are mitophagy (2 studies).
Mitophagy
downin cells2
Amyloid-beta 40 decreases mitophagy in cells.
“amyloid precursor protein (APP) or Aβ40, but not Aβ42, shows increased proximity or co-association with TOM20/TOM40 alongside reduced mitochondrial CerS1/C18-ceramide accumulation and mitophagy.”

EMBO reports
Amyloid-beta 40 inhibits mitophagy in cells (lipid stress-mediated hyperactive mitophagy; requires mitochondrial localization of APP).
“its cleavage product amyloid-β 40, but not mutant APP that lacks a mitochondrial localization signal, inhibits lipid stress-mediated hyperactive mitophagy in aging T cells”
