If you can benefit from including multiple bank accounts, in your case provenance of funds and transparency, then of course. There is no requirement to submit statements from a single account.
My expenses are all on credit card except for rent, so do i need to submit credit card statements as well?
They are not interested in constructing your personal balance sheet and credit card statements that show only expenses are not necessary. The UK officer will ignore credit card statements altogether; the Schengen officer will examine them if you have large credit balances that you want to present as accessible cash.
I do not want to overload my documents submitting too many bank statements or submitting any irrelevant ones
Based on what you wrote, you should show both accounts. This is not 'overloading' your supporting documents.
