I don't quite understand the "lack of Scrum in large companies" when they all seem to Plan-Ship-Build. That is pretty much the high level description of Scrum isn't it?
Sure Scrum has some ceremonies, but these are basically planning and retrospective for improvements, so again, not really any different.
At the end of the day, most of the ways I have worked end up with Tickets/PBIs/Stories and you work through them. The only major difference is how much in-advance these are specified and to what detail.
I’ve worked at a couple big tech companies and one scrum. Notable differences, much less ceremonies, planning is also more up front with deviation allowed but not needing additional planning, and ticketing being optional thing that varies by team.
I do not usually track my current task with a ticket or story. I have once week meeting with my team to discuss what I did last week and what I’ll work on next week. There is no 2 week sprint/constant stand ups/individual ticket estimates/retro. A typical plan is for a project that will take a month on short side or 2 quarters on long side. Deadlines tend to be soft with it culturally accepted that most deadlines are rough estimates and a week or two so deviation being fine. Process feels very light for me and I’m pretty happy with that.
