Let go of having to have an opinion about everything. Pick your battles. Save your opinion for when it is really important to you. It can significantly up the "delight factor" in your marriage (and even sometimes add a lot of fun to the relationship) to just support your spouse's opinion or choice--not even voicing your own--just supporting theirs! If you value their thinking, then you can trust that their opinion might be just as valid as yours--even if you disagree. And the reward to your relationship will often be worth a lot more than what you gave up.
