See the updated sample code as below:

If you have single selection for User and Group field and for Choice field then create data as given below

function createEmployeeDetailsListItem(excelRow) {
var data = {
    __metadata: {
        type: "SP.Data.E2EVMVulnerabilitiesMappingMasterListItem"
    },
    Title: excelRow["Title"],
    ID: excelRow["ID"],
    DateCol: new Date(excelRow["Datecolumn"]).toISOString(), //Datecolumn
    PersonGroupColId: excelRow["Persongroupcolumn"], //here you need to set the Id of the Group or a User (For single user or group selection)
    ChoiceCol: excelRow["Choicecolumn"] //Choicecolumn, here you need to set you Choice as a Stirng "Choice 1" (Only work for single Choice selection)
}

$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('Test')/items",
    type: "POST",
    data: JSON.stringify(data),
    headers: {
        "Accept": "application/json;odata=verbose",
        "Content-Type": "application/json;odata=verbose",
        "X-RequestDigest": $("#__REQUESTDIGEST").val(),
        "X-HTTP-Method": "POST"
    },
    success: function(data, status, xhr) {
        console.log("success");
    },
    error: function(xhr, status, error) {
        console.log("error");
    }
});}

If you have Multi selection for User and Group field and for Choice field then create data as given below

function createEmployeeDetailsListItem(excelRow) {
var data = {
    __metadata: {
        type: "SP.Data.E2EVMVulnerabilitiesMappingMasterListItem"
    },
    Title: excelRow["Title"],
    ID: excelRow["ID"],
    DateCol: new Date(excelRow["Datecolumn"]).toISOString(), //Datecolumn
    PersonGroupColId: { 'results': excelRow["Persongroupcolumn"] }, //Here excelRow["Persongroupcolumn"] is array of multiple choice - When you field set as Allow Multiple
    ChoiceCol: {
        "__metadata": {
            "type": "Collection(Edm.String)"
        },
        "results": excelRow["Choicecolumn"] //Here excelRow["Choicecolumn"] is array of multiple choice - When you field set as Allow Multiple
    }
}

$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('Test')/items",
    type: "POST",
    data: JSON.stringify(data),
    headers: {
        "Accept": "application/json;odata=verbose",
        "Content-Type": "application/json;odata=verbose",
        "X-RequestDigest": $("#__REQUESTDIGEST").val(),
        "X-HTTP-Method": "POST"
    },
    success: function(data, status, xhr) {
        console.log("success");
    },
    error: function(xhr, status, error) {
        console.log("error");
    }
});}
