Please educate me how resize would be different from any other command of fdisk that actually manipulates partitions (as opposed to merely displaying stuff)? This is a tool that lays out new partitions, of course the contents may be lost! But, resize actually is different: it doesn't destroy contents, merely the part past the new size. So do resize the contents first! This is a low-level tool, it doesn't know how many storage layers you have atop the partition block device so it can't do that for you. Use a clicky-clicky tool if that's hard, but be prepared with those being confused by anything but one-simple-filesystem-per-partition.
