Lightning network inbound liquidity question

Finished syncing a full bitcoin core node not long ago and set up lightning network. Have not opened any payment channels yet because my concern is inbound liquidity. What I’m wondering is. How to go about it without just opening random channels.

My main goal is to support decentralization. Just to set up one reliable node that can route day by day transactions. Is there a way to avoid much dependence on centralized swap services? Would like to avoid third parties if possible.

I don’t mind the kyc. Even me personally I don’t and have never done non kyc transactions. I totally wouldn’t judge anyone who does. Main concern is I don’t support any weakening of the network. I don’t like anything that helps or uses services that are too centralized and vulnerable to government intervention. Plus the fees and limitations. Mostly the fees.

Has anyone had experience and success with submarine swaps, like peerswap or lightning loop. It seems like a lot and wonder if very many just don’t get into it.
