Performance wise you should see an increase of up to 15% with most applications. The M2 runs hotter than the M1, so for sustained load tasks, it may end up being a bit slower. However for the reasons you bought this machine it is still worth the upgrade. You get MagSafe and a bigger, better screen, better speakers and nicer design plus an increase in performance for day to day things. Depening on your use case the loss of the touchbar may also be a positive. If I'm guessing right your work will involve a lot of opening and closing of documents and the M2 Air will be able to handle it perfectly fine I think.
