2 years Citi BBVisa: CLI, App for new or Garden?

[Gratitude]

My second oldest card: Citi BBVisa, is now 2 years old.  Never late payment, $0 reported balance,

After 2 CLI’s (never declined), current CL = $11K

Currently eligible for another CLI.. but a CLI will cost a HP for sure (As this forum says & confirmed by phone with CSR).  If that’s the case, would it be wiser to simultaneous app for new Citi product at the same time of the CLI request? [like maybe Double Cash card ?] 

Note:  CSR says CL is not eligible for tranfer to new Citi product outside of BB  products (which I have no interest in).

Concerns:

(A)  Keeping Inquiries minimal (and old) as I am soon to app for a Business Line of credit;

(B) If going to app for another CC, do I really want Citibank card.. when eligible for majority of cards ?
