What exactly do you enjoy about fantasy media and what game allows you to enjoy it?
Emotional / spiritual conflict
Cost of using magic may incur a risk (possibly a physical toll)
Weapon choice playing a greater role
Limitations of magic and magical power
Bulk and weight are significant limitations
Importance of mundane equipment
Comeliness plays a role
Exhaustion is far more common
Slower recovery of health
As to your second question - I have not been fortunate to experience many fantasy systems within the D&D genre. Some I've read but not played...
But I like many ideas from a variety of games which can be retrofitted into D&D. Games such as Torchbearer, Vampire Dark Ages, Summerland, A Song of Ice and Fire RPG, Grimm, Pentagon. This is besides the 3pp which exist for 5e, 3.x or OSR derivatives.
EDIT: To be clear I'm not retrofitting or homebrewing anymore. I've decided my games after the current one will be a mish-mash of ideas with an entirely new engine of my own design.
