Don't have experience with Jade, but sounds good to use Sparrow or other coin control-supporting wallet software paired with the Jade to sign the transactions.

It supports cc... seems good so far. Thank You!!

I need some advice on cold stored kyc and non-kyc BTC

Good to hear!
Addresses cannot be linked back to a common xpub by themselves unless they appear in the same transaction graph.

Be very careful and use a wallet that supports coin/UTXO selection and send *only* the non-KYC coins to another (new?) wallet. And do your best to NEVER accidentally put KYC coins into the empty address left behind. Wallets should typically avoid reuse AFAIK but you could go extra paranoid and also move the KYC coins to a new wallet and retire the old one to completely avoid that risk.
