저는 uses the topic particle 는, which marks me as the topic: as for me or speaking for myself.
In this sentence, the speaker is talking about their own reading habits, so 저는 sounds very natural.
If you said 제가, it would put more focus on I as the subject, often with a nuance like I (as opposed to someone else) or I am the one who.... That is possible in some contexts, but 저는 is the more neutral choice here.
요즘 means these days or lately.
It usually appears near the beginning of the sentence because it sets the time frame for the whole statement. Korean often puts time expressions early in the sentence.
So:
저는 요즘 종이책보다 전자책을 더 자주 읽어요.
= As for me, these days, I read e-books more often than paper books.
You could move 요즘 in some cases, but this position is very natural.
