People assuming the wizard takes 4 of every level after 1st level spells have likely not actually played a wizard. Sure, that is likely true of 2nd to 5th Level spells, but you don't need an army of high level spells when you only have one spell slot of those levels.
My wizard's progressions have both been very similar. You start with one or two combat spells and a few rituals in your first level spell book. Then, through about level 6 you pick towo new spells of the highest level you can cast. Meanwhile, you find a few more spells to add to your spellbook - sometimes deciding not to spend the gold to put them in your book. Rituals are great because you can cast them without slots, but there are a lot of non-rituals that may not ever make the cut, so why learn them from an efficiency standpoint?
Level 7 is the first time you get to a point where you only have one slot of your highest level spells. For the first time you might not decide to take two spells of a level where you can only cast one at a time. Afterall, you can only prepare 10 or 11 total spells. Do you want two of those to be 4th level? I found it hard to justify preparing two 4th level spells. At 8th level you get two extra prepared slots (if you raise int) and it becomes easier to justify preparing 2 or 3 4th level spells, but you may already have a good selection through found spells.
At 9th you get that first 5th level spell, but you're only going to get two 5th slots until you hit 18th level. You have eve. Less incentive to take 2 spells of 5th level at 9th level. However, there are some good 5th level rituals, so maybe both of your free spells are 5th level. However, from there on up, you're balancing the number of slots you have versus the numerous of spells you can prepare to help decide what to take, and you start thinking more and more but fleshing out low level conditional spells.
Unless Yu also change the numerous of spell slots or the number of prepared spells a wizard gets, the 2 spells per level is really fine.
