Is a 7ft net height better for a beginner?

Hello, I recently decided to pursue volleyball as a hobby. The thing is, I’ve never played with an actual net. I planned on buying a shorter adjustable net but options are limited. I assume around 7ft or higher for casual play is best but I am pretty short and can barely jump at all for any sort of spiking. Is this just a skill issue that can be fixed through training on jumping higher or would an adjustable net work best for me? I only want to play casual with friends and family which is why I would’ve wanted to buy a shorter net for better spikes and gameplay. Thank you.
