Across (at a 90) is perfectly acceptable, to code and has almost zero chance of causing interference.

To be clear, I am not recommending that you go unshielded where there is that much EMI, I'm just saying I have been in situations where that happened, and it was at 90 degrees, parallel, and various angles crossing. These were on sites in rural South Texas with people running these lines who typically ran commercial electrical lines.

It is also where I saw the difference a properly terminated RJ45 connection can make. This was at least 15 years ago, probably longer. A lot of guys would simply match colors without regard for terminating the pairs properly. Nothing like an MCC to show you the error of your ways there.
