Yeah, personally, I mostly agree with your assessment as well.
The United States' view on strategy has always had a tension between the maritime power view and the continental power view.
For a maritime power (the US approach we've seen most of recently since WWII ), it's practically a no-brainer to invest heavily in the Ukraine conflict. It allows the US to degrade a rival's military abilities at low cost; it maintains the balance of power in Europe without direct US troop involvement; and it upholds the norms against territorial conquest that benefit maritime powers.
If the US is seeing a resurgence of isolationist/continental thinking, then you get different arguments: The conflict is distant from US territorial interests; border security and domestic concerns become more pressing; and regional conflicts elsewhere become mostly just distractions.
