OK - keep in mind that the tolerance in electrolytic caps is typically +100%/-20% unless noted otherwise.

Your larger caps will be just fine.

There are two things wrong here.

First this is an AC motor with AC capacitors. Electrolytics will not
work on AC as a general rule.

Newer capacitors, especially motor capacitors are much closer now in
tollorence.

I have one here that is rated +- 5% I keep as a spare for my heat pump.
Many are rated for a range of capacitance of about +- 10 % now.
