Data recovery from old Samsung Galaxy S2 (GT-I9100)

I have recently found one of my very first Android phones, a Samsung Galaxy S2 (GT-I9100), with many fond memories saved onto it. Now, I can not access the phone's data anymore since I entered my pattern wrong too many times back in the day. Now, even if I enter my current Google credentials for the account I used during those times, the phone doesn't want to acknowledge that. I have double-checked several times that the password I entered was correct. Since I don't seem to be able to access my phone via normal means, I was curious if there is a way to recover my data another way. I don't mind if the phone becomes unusable afterward as well. I have only very limited knowledge of Android and all its abilities, but I seem to remember reading about these older phone's storage being easier to access than newer ones. Is there a way to recover my data? Even any idea why my phone asks me for my Google login but doesn't accept it would be helpful. I would really appreciate any help since those are a lot of memories that would be lost forever.
