How dangerous would it be to hike a mountain in Washington state as my first mountain?

I live in Florida and have never hiked a mountain before. I have done some hiking in Colorado before but mostly easy trails. I’m 19 years old and in pretty good shape, I do cardio every day and am an active person, so that is not one of my worries. I will be visiting Seattle mid June. I have been doing some research and I’m thinking of either trying sahale mountain, Eldorado Peak or Mount Adams since they’re supposed to be some of the easier and non technical ones from what I have seen. How dangerous is avalanche risk? Will I likely find crevasses that time of the year? I would be hiking with my girlfriend who also trains regularly. If anyone has hiked any peak of Washington state that they think is a better first mountain I would appreciate it.
