Not really. In most trades you also get to keep the trading partners first round pick. I.e. KC traded for Mahomes and the Bills received the KC's 1st round pic + an additional 1st round pick the following year and a 3rd round pick.
The value largely depends on which 1st round pick you trade and with who (how far do they have to trade up). If there is only a trade up of a handful of spots outside the top 10 you most likely only exchange first round picks and get some 2nd rounders, 3rd rounders etc.
Even if you look at the Jets/Colts trade for Darnold. Jets and Colts traded 1st round picks and the Colts got three additional 2nd round picks.
If you want to have an additional 1st round pick for 2021 you have to find a trading partner who is in need to jump a bunch of spots (i.e. KC which jumped 17 spots).
