Things I don’t like about Google CSE, and is there an alternative?

Hello, Bros,

My issue is,

I am using Google CSE to search a certain list of websites on the internet…(not in my website or anything fancy like that)

I came across posts saying that I shouldn’t enter more than 20 websites

https://support.google.com/programmable-search/thread/3082211/cse-domain-limit-reduced-from-5-000-to-20?hl=en

Maybe I am misunderstanding… because I am not exactly sure that it has affected me…??
My list is around 200 websites… am I utilizing them all?

I also have another problem and that I am only limited to 10 pages, 10 results per page..
That is a joke…

Can I change that ?
SEMrush

if i cant, is there another service that will give me serious results?
I need a service that provides me with much deeper reach and atleast a 1000 results,
and a huge database of websites I can input..
