There's a number of ways to approach this, complicated by the fact that Rance IV and 5D don't have remakes, and the question of where to place Kichikuou, which isn't canon.
IV and 5D aren't necessarily bad, but they're sort of dated, and can be frustrating, especially for a new player who isn't as invested in the series.
The most straightforward route would be 01>02>03>IV>4.x>5D>VI>Sengoku>Quest>IX>X.
The machete order here would be to skip IV~5D, and play Kichikuou instead, going 03>Kichikuou>VI, and is my personal recommendation.
I/II/III are skippable for the most part. 01 and 02 are outright upgrades to their old versions, and III isn't really necessary if you've already played 03 anyway.
