underclassmen-internships VS tech-interview-handbook

Hi everyone. I am an incoming freshman at a T50 university studying CS and looking to go into SWE/Quant(the latter part would require a transfer up). I have seen several posts on this sub saying that I should start looking for freshman internships now. I'll be entering college with an internship and research experience(going to be done within a professor's lab at the university I will be entering in the fall) during consecutive summers under my belt. I understand the market is pretty bad right now and thus getting an internship during the summer after freshman year will be hard. Due to some scheduling issues/limits, I won't be able to take DS/Algo during my first year but I will be self-studying during the year - hopefully to the point that by the end of the year, I can solve Leetcode Easys with a decent amount of confidence. I have found a repository like this: https://github.com/codicate/underclassmen-internships that has a lot of opportunities for freshmen but if anyone has any other databases/places where this information is consolidated that would be helpful. I also think I will have an opportunity at a semi-big company next summer mostly due to nepotism/family connections. Is that something I take? Do I sort of punt on this year for internships and come back with a very strong resume for the summer after sophomore year(where I would aim for FAANG even though that is unrealistic), and take my freshman year to work on projects and flesh out my tech stack? Additionally, what are other things I can do to make my resume stronger? I'm looking into TAing for my school but it seems they don't allow undergrad TA's based on my search so that might not be an option - so it might just be projects/hackathons/club involvements. Any advice in my search would be considered very helpful. I can also post my modified HS resume(and projected freshman resume) if needed.

We are currently following the tech interview handbook , currently on arrays and practicing sliding window technique.

Tech Interview Handbook is another resource that would be helpful.

As per title, I am looking out for good interview resources for machine learning engineer. In software side, I have heard of https://www.techinterviewhandbook.org/ to be one of the best.
