Secure lightning wallet

With the fee market working as designed and higher fees are inevitable for on-chain transactions, what is the best way to dca to cold storage while utilizing the lightning network?

I currently dca with strike and send to hot wallet then cold card using a blue watch only wallet. I don’t have a node yet so for now I’m using WoS for a lightning wallet for any ln tx I need to do. I use ln wallet as cash in my wallet, hot wallet as checking account and cold storage as savings. I’d like to continue without using so many on-chain tx. For now I’m letting my dca stack on strike before paying 800+sat/vbyte to get it off the exchange.
