Lost benefits, only qualified for PHCS limited coverage. Is this my best option?

I recently switched from being a full-time employee to having multiple PRN jobs at various health facilities. My husband was also on my insurance plan, so unfortunately we both were in need of insurance. I checked out the marketplace plans and also spoke with an insurance broker to determine the best course of action for our situation. Ultimately we went through the broker who set us up with the approval process via United Healthcare. Despite being young and (what I consider) healthy, I was denied coverage for a PPO plan because of a medication I am on. Instead I qualified for United Healthcare PHCS limited coverage. I have run into more difficulty than I expected trying to find providers who will take my new insurance. And based on some other info I am reading, I feel that I may be lacking a full understanding of what my “limited plan” covers, especially if anything catastrophic were to occur. As a healthcare worker, I am well aware of/terrified by the potential for devastating medical debt that could occur without enough coverage. Considering my situation, I just wanted to ask some professions (who aren’t making money off of me), if my current plan is in fact my best option or if perhaps the marketplace might be better suited.

My plan costs $310/month, my husband’s plan costs $275 (total $585). The marketplace plans started in the mid $600s for us combined.

And in case this is important, I am currently taking escitalopram for anxiety and pregabalin (generic lyrica) for idiopathic neuropathy. The pregabalin is the reason I was denied. I had a myriad of tests performed to rule out possible causes but none were found.
