You have a great scope there Peter in the 10”and should be able to resolve many DSO’s without the need to upgrade to a monster of a telescope in the 16”
I had a 10” non Goto dob for years and recently upgraded to a 12” Goto which is a big as I will ever need
Firstly to observe most DSO’s you need low power eye pieces from 17mm up to 30mm
My favourite eye piece for nebula and globular clusters are the ethos 21mm and for galaxies my 24mm and 27mm Panoptic. Sometimes I use the Delos 17.3mm but not that often

Planetary require medium to high power eye pieces depending on seeing conditions in the 13mm to 4.5mm range. I use my Ethos and Delos eye pieces for planets
For lunar just about anything will do and again seeing conditions determine what’s best
To add to the range I have a set of Televue Powermates plus various UHC and planetary filters

It’s entirely up to you but your 10” will do the job nicely provided your not chasing +12 magnitude objects , the real dim faint fuzzies
Hope the above helps
