Sending a transaction from one of our addresses to another will cause a connection, not limited if it’s our own address or an address from someone else.

There is no way for blockchain analysis to know why a transaction was made from BTC address A to BTC address B if both addresses aren't KYC-ed. They don't even know if the same person owns both addresses or coin ownership happened. But following the money trail might lead all or some of the coins to land on an address connected to a real person who underwent KYC. At that point, the coins might have changed ownership several times.

And here, we have also to consider to be very careful. Seizing such services will always be a risk to bust our privacy. If privacy services are seized, it'll always be a risk of mixing logs to be leaked and address connections to be revealed.
As it happened to ChipMixer, when several Terabyte of data was collected, among it very likely logs but also private keys (Chips from ChipMixer), where several customers of ChipMixer have reported about coins from such "Chips" being transferred to a different wallet.

Not if there are no logs to seize. If a service claims it's not keeping logs but still is, it's worth asking why? Perhaps that lie is their bargaining chip. If they get arrested/charged, they can say, please be lenient to us, and we will give you logs of the people who used our services for a lighter sentence. This is more a question of honestly and ethics than anything else.

Last thing I remember, there was one wallet that uses conjoins, but then a good deal of privacy leaning members don't trust it because, there is talk of zkSNACKs its coordinator blacklisting "tainted coins"

How is that decentralized and trustless? Educate me

Wasabi's zkSNACKs coordinator isn't, and it funds blockchain analysis, the enemy of Bitcoin and privacy. However, JoinMarket is. It's also more complicated to set up, and surely has a smaller userbase.
