The only solution I can think of is to maybe pre-order Endwalker now and get the pre-order bonuses and use them during the free trial. So only in your 4th month of subscription, you can finally enjoy Stormblood, Shadowbringers and Endwalker.

However, this is based on a free trial player who has done LV 1-60 content fully and may find less satisfaction reliving the SE content for 3 months straight till the release of Endwalker and still paying an active subscription for 2 months. If only pre-ordering Endwalker meaning access to Stormblood and Shadowbringers immediately after purchase then after the release of Endwalker, you could use the 30-day free period to enjoy the new expansions. Therefore, if your end goal is to conserve money, you will have to be aware of the 30-day free period and the active subscription cost of the SE, in conjunction with the cost of pre-ordering Endwalker and the cost of buying the SE. Hence, between the end of the 30-day free period and the Endwalker release date, you have to pay the monthly subscription of the SE. Meaning you might waste the 30-day free period if you have done most of the LV 1-60 content during the free trial between now and the release of Endwalkers.

If you buy the SE now you get the 30-day free period, the amount of content in the SE is the same in the free trial except for the social-economic limitations. If you are a free trial player, I found a small caveat.
