Behringer makes really good PA speakers for a rather cheap price. But I don’t know exactly what your price budget it - they’re good but they’re not great. They’ll do for house parties if you get the 210’s or 212’s but i wouldn’t recommend dropping money on the 215’s and instead get like mackie thumps.
Yo.. I have had some bad experiences with Behringer products.. unfortunately 
Also.. some of my mates have too… Didn’t notice what your budget is, but if you’ve got 700 bones to throw at the problem, a pair of used FBTs might be your best bet.. these are Italian speaks which were the design basis for the Mackie SRM 450’s… They aren’t as powerful, but they sound super clean… and the bigger woofer moves more air which means outdoor parties will rock harder… Now… if you’ve really got a big budget… 
Behrginer products, or just behringer mixers?
amps and speakers made by behringer are amazing pieces of kit,
Bar the DDM4k and possibly the new NOX series, they have made the worst mixers known to man
But amps + speakers = yay
That is quite a wide range of venues you have listed.
In general, the best compromise for mobile DJ work is dedicated tops with subs.
The default advice for a PA system will be the B52 Matrix 1000v2. That system includes two tops and a sub, and all the electronics needed to make it work. You will need speaker stands, and some longer cables. Figure $1k out the door. That system will handle parties to about 2500-3000 sqft with 150-ish people. For smaller venues, turn it down at the mixer.
If you are planning to expand much beyond those venues/crowd sizes, the passive speakers with external amps & electronics are a better value…and the value increases as the system scales up.
Behringer got a reputation for bad quality by earning it.
In recent years, they have made a good turn around with some reliable gear. I think it is a mistake to offer a general warning against Behringer at this point, especially for people with limited budgets who need entry level gear.
The SRM450 is OK at best. The low end rolls off really fast below 70Hz, and the mids are not clear enough for my taste. I have not heard the FBTs for comparison.
Outdoors, the rule of thumb is to being 2x to 4x the cabinet count to keep “similar” SPL levels when compared to indoors. A pair of powered tops on sticks will not rock an outdoor party.
My sentiments exactly.
With you here as well… there seems to be a soft roll around 180hz to 300hz depending on how much low end the driver is trying to produce.. white and pink noise produce a flat signal though.
In my opinion I feel the sound of the FBTs is more transparent. Also, the high frequencies have a vivaciousness that the 450’s lack. I find 450’s can be harsh around 1khz - 2khz range. As with the 450’s there is a roll-off below 70hz, but my ears tell me it is much a much shallower curve than the 450’s… Actually.. I just finished a sound check for a mobile setup tonight. Big room 75’ x 35’ x 40’ (high) Sound tech provided 4 FBTs on sticks with one 18" JBL driver in a custom sub cabinet. The FBTs hold enough of their own so we crossed over at 78hz with a shallow curve.. Sub is only needed for fill and at Neg 2db with the room empty… probably increase it to +2 when the room fills up.. the FBTs produce a nice fat low mid section with flat eq settings..
= everyone standing still.
Mackie TH-15A Thumps
Get a pair for $600 and never look back.
You can add a subwoofer later to really push it if you need it to be louder for more people.
