Yes, for a machete, I'd definitely prefer a bit longer of a blade than ~12".
As Elliott mentioned a 15" blade for an all-purpose machete is a good start.
I've used even longer Latin machetes in the ~22" blade range, but what I've found personally, was that the longer machetes are going to be biased more for thinner/lighter blades suited best for brush and lighter foliage, with the shorter machetes able to have thicker, comparably heavier blades that allowed for more varied use.
My dad had an old British made machete. Can't recall the name of the manufacturer, but I recall seeing the "Made In Great Britain" stamp. Thicker ~16" blade that had a great combo of swing speed for brush and light saplings, but much better chopping ability than a standard 22" blade Tramontina.
Similarly, I kept my Behemother and sold my Behemoth, because while both have 12" blades, the Behemother has significantly more chopping power, while I personally felt the lighter swing weight of the Behemoth, but with a 12" blade, made it a little too short for my preferences as a wide/varied use heavy machete.
It's one of the reasons I'd asked a while back about you mentioning a longer LC. I LOVE the LC's blade profile, and would absolutely be down for a ~15-18" blade version.
