Well, around here, we'll always advocate for the CompTIA branded stuff. But if you can't do that right away, I would recommend sites like Cybrary and Udemy to get started, if you're looking for "talking-head" lecture.
As @Stephen P would say, Course Objectives + Google = Study Guide. That works pretty well, particularly for new tests like the upcoming Cloud Essentials+, Server+, Security+ and CySA+ updated exams, all of which may be short actual published material, but again, you can just run through the objectives and start studying from there.
Once you're ready, you should just be able to go out to the A+ page that I linked, buy the voucher for wherever you are, go take the exam, then go prepare for the other one. Remember that A+ is a two test certification.
