"And *some* of the income form IRA retirement accounts related to work done in US as well."
Presumably the funds in Rollover IRAs (transferred into IRA from 401k plans) could 100% qualify as effectively connected income (assuming you wanted to bother filing).
On a related topic, another situation where I think you would have no choice but to file a 1040nr is in the case of Roth IRA distributions. I think most custodians will withhold either 15% or 30% if the funds are sent to a foreign address (or at least that is my understanding). The only way of getting this money back would be to file a 1040nr listing the distributions as NEC income at 0% rate. Is this also your understanding?

Well, regardless of the withholding, you would not report it as NEC, you would report it as non-taxable IRA distribution on page 1. It's not a treaty rate.
As explained above some Traditional IRA income is considered NEC, presumably the gains above contributions.

After 20 years, I am severely cutting back on responses. Do not ask specifically for my help. There are a few others on this board that can answer most questions. All the best
