My biggest feeling about "cross-chain" right now is: as long as it works, that's fine, but don't trust it too much; assume it will encounter problems. Frankly, when doing a cross-chain transfer, you’re trusting not only the bridge's contract but also how the messages are verified, whether validators/relayers might act maliciously, whether the light client is correctly implemented, and whether the target chain might get stuck due to upgrades or pauses... The more steps involved, the more stable your mindset needs to be.

I quite like the approach of IBC, which clearly explains the "message passing" process; at least you know exactly what you're trusting. But even so, you still can't avoid trusting the security and implementation details of the other chain. Recently, there’s been intense debate in the community about privacy coins, mixing, and compliance boundaries. I’d rather think of cross-chain as "a usable but risky infrastructure": avoid unnecessary steps, and if you do proceed, do it in batches, with small amounts, and leave room to back out—don’t gamble on system complexity with luck.
