Is it worthwhile to consolidate your entire cold wallet into one UTXO?

No. Follow The Middle Way.
I’d recommend 100 bitcoins utxo chunks
I have mine split up into ~5-6 largish ones just since I have gone through the trouble of trying to anonymize each. That way I dont dox myself and my stack size when I eventually spend.
No it’s bad for privacy
A stack of 100s and a few 5’s.
Personally, I don’t recommend consolidation (Privacy).
Maybe if your inputs came from the same source, then it’s less of an issue.
Its nice to spread utxos across addresses imo
If your UTXOs are small, yes. If they're like, 5M or more a piece, maybe not. "Small" is highly subjective, but I'd say anything less than 1M is small.
I did a few years back. There are only a couple utxo's in my coldest stack.
So, the next time you make a purchase, they'll be able to see your total balance? Better stacking 1m sats at once at least IMHO
