I'll give you guys the advice that has helped me land a research gig at one of the nearby MD schools. Your situations I don't think will be as bad as mine.
1) Figure out what types of research you want to do (if uncertain and are considering a hyper competitive field look for a broad topic like cancer)
2) Start looking early for a mentor (a few months into first semester)
3) Look at google scholar and pubmed for publications --> it will give you a talking point in your emails and you will know how productive in research your mentor is
4) Talk to a school mentor about how to frame your email --> I did this and my mentor was helpful (I didn't need much tweaking since I am used to sending formal emails to people).
5) As mentioned about, talk about your interest in the field and their research in your email --> this will help give context to your email and prevent it from being bland. However, don't make the email too long otherwise they will be turned off.
6) For the CV, make sure you run it by your school mentor also. My mentor gave some good tips (I was used to writing resumes so, there was barely much for her to say to help improve it more). Make sure to front load your most relevant experiences (first pages of CV) and most recent ones.
7) Make sure you are at an okay point before pursuing research (most people in my school started 1st year second semester or summer)
Don't mention about the lack of experience on your initial email. It should show your enthusiasm about working with the research. They will ask you about your research experience later and then just tell them you don't have any currently, but are willing to learn. They care about your enthusiasm more so than your experience.
Remember most important thing is surviving your classes first, research comes later. Good luck
