Joining NATO is widely regarded as the safe and rational choice. Russia already saw Finland as part of "the west" and Russia's attack on Ukraine meant that our international relations with them were pretty much destroyed. Staying out of NATO made no sense from that point onward. Why try to stay "neutral" with no formal defense pact, when Russia viewed us as hostile anyway?
So yeah, I would say that the vast majority of Finns feel safer now, and becoming a NATO member has been seen as a positive thing overall.
