I've tried Armory around 2016-18, I found it very difficult to use, it never synced with my node and it seems that the code has not been updated since 2018, which makes me think that the devs have abandoned its development, it would be a more amazing wallet than it was in the past, what a shame.

Anyway, from what I've seen you can export the private keys of the addresses in armory, but they are not in WIF format, they are in base58 and/or hex format, when doing so, you must convert the exported private key format from base58 to WIF which is recognized by most wallets.
