What are the de facto advantages of Sweden and Finland joining NATO?

There is a plethora of news about Turkey opposing Sweden and Finland from joining NATO, suggesting that this will be quite a long process.

Being part of NATO offers an important advantage (besides others) due to collective defense (article 5), but I am interested mostly in the de facto advantages here based on the following rationale:

• NATO successfully rolled out arms in Ukraine, a non-NATO member, which had an important role in pushing back the invading Russian army
• Both Sweden and Finland's armies ensure interoperable capabilities with NATO, so I guess NATO helping them would be even easier than in Ukraine's case

That means that NATO (+ others interested to help) can effectively help a country resist a Russian invasion regardless of NATO membership.

Is there anything on the practical side that brings NATO membership for Sweden and Finland on the short-medium term (1-2 years)?
