"sarcoidosis"
Yep.
And also a real, fungus infection called histoplasmosis. Are you in the Mississippi River Valley? Ohio River Valley? Neck nodes aren't common, but rarely can be: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687211/
Then also TB, or a mycobacteria that is like TB but isn't TB.
Sarcoidosis and TB do both come to mind when there exists lung granulomas and cervical nodes. TB wasn't as common ~20 yrs ago as today, though.
Why did you have the CXR at 4 yrs old?
This probably increases the possibility that your neck nodes are granulomatous and less likely fibrosis. Or both. Your FNA mentioned neither, right? With this new info, probably a core needle would have been better - as it gets a core sample of tissue rather than just isolated cells.
"Table 1 shows 16.8% of 'oval' nodes as being benign."
Scratch 'oval', that should say 'round' instead.
Also from that table, S/L ratio ≥0.67 is benign in 35% of cases. Whereas your ratio is less round at only 0.58
"...is having a little calcifies spot in soft tissue worrisome assuming it isn’t a node?"
I don't know but I doubt it.

Table 1 shows 16.8% of 'oval' nodes as being benign.
"Also is 2.4 by 1.4 by 0.8 cm large? ... isn’t that long to short ratio bad?"
True, technically, it's less than 2 to 1. But I wouldn't think it's a hard and fast rule. Somewhere there might be a study that lists individual subject's data, and likely there are some that are less than 2 to 1 but are still benign.
"Turned out that’s not even a node. I guess it’s just calcified tissue?"
Hard to believe from my end, especially since there have been three different opinions on that. Still, it is possibly true, and is likely inconsequential.
