Nuggets:
Nuggets lack a lot of things and there is a good chance the draft can help. As for why they should draft over look at FA, Murray, AG, and CB are going to be heavy contracts in the not-so-near future and bolstering the bench with proven FAs will become too difficult, especially for solid roleplayers. Trading their valuable 2031 FRP for 2 late firsts can help Denver field for a potential rim protector and ball handler off the bench. As for Watson and Julian, these players are still unpolished as players at the same position which is less problematic to replace than the Center position. Jerami Grant provides solid ball handling and defense to the position whilst DJJ is an athletic POA defender Denver can trust. Bruce and Kornet would be desirable for their sparkplug nature (Offence for Bruce and Defense for Kornet) off the bench.
Nets:
Assuming no shenanigans from the Nets FO looking to get suddenly competitive, the team should be looking to tank and continue to acquire valuable picks for their warchest. The 2031 FRP of Denver is as valuable as it gets imo as the team will likely just be bad when Jokic and co. are out of their prime and out of the league. I think its fair to get 2 late FRPs for a potential (if not likely) lottery pick when the Nets should be a competitive team. They can also afford to have Nnaji, Hunter, and Keldon as they have so much cap space they can just ride out or buyout their contracts whenever they want.
Clippers:
This team (like the Nuggets) has no bench and is also very old. Getting some young bench players like Strawther or Watson (Shooting or Defense your choice) and Timelord as backup C would help cleanup some issues w/the second as an extra asset. DJJ was great and all on defense but just cannot be trusted to shoot which the Clippers desperately need in general.
Trailblazers:
Portland can get off of Grants long term contract for some a decent expiring player in Barnes and a potential defensive sparkplug in Watson (or if you want a shooter Strawther). This trade cuts their salary in half and gives more space for the team to begin extending or signing new contracts for their franchise players. If you think its too little then Denver can add a 2030 pickswap with the Blazers giving out another second.
Spurs:
Spurs pay very little for a high upside player in MPJ that is lights out from three with incredible positional size and rebounding. With Fox, Wemby, Castle, and soon-to-be Spur Dylan Harper on this team, MPJ would make the team even more of a pain offensively with MPJ's defensive problems less of a problem thanks to Wemby being a deterrent at the rim.
